Common optometry methods in Shanghai Eye Hospital
Optometry is one of the most common and important examination items in ophthalmic hospitals. It is of great significance for detecting vision problems, matching glasses or optometry surgery. As a world famous ophthalmic hospital, Shanghai Eye Hospital has advanced equipment and professional medical care team, providing a variety of optometry methods to meet the needs of different patients.
Top down optometry
The top-down optometry, also known as objective optometry, measures the optical properties and refractive state of the eye through the use of special instruments. This method does not require the patient's subjective cooperation, and is suitable for infants, mentally disabled people and other patients who cannot cooperate.
Shanghai Eye Hospital uses Doppler biometry in the top-down optometry to measure the length of the eye axis, which is a non-contact method that can quickly and accurately measure the length of the eye. At the same time, Shanghai Eye Hospital is equipped with * advanced wavefront phase difference meter, which can also measure the corneal refractive state through wavefront phase difference measurement.
The top-down optometry is of great significance for screening eye problems such as refractive problems, corneal and lens abnormalities, and can provide doctors with more accurate data for diagnosis and treatment.
Conventional optometry
Routine optometry is a common subjective optometry method, which requires the patient to actively cooperate with the doctor to determine the patient's refractive error and the best correction degree through different experimental devices and measurement methods.
In Shanghai Eye Hospital, doctors will use an automatic refractometer to measure patients' refractive status. This instrument can quickly adjust different lenses and lights to obtain good vision and help determine the degree of glasses required by patients.
In addition, Shanghai Eye Hospital will also use an eye chart to measure the vision of patients to determine the degree of correction required by patients.
Corneal topography
Corneal topography is a non-contact method for evaluating corneal curvature and shape. Shanghai Eye Hospital uses a new corneal topographic mapping instrument to measure the curvature, height and shape of the anterior surface of the cornea in order to evaluate the refractive state of the eye and corneal related diseases.
Corneal topography is of great significance for the early screening and treatment of corneal diseases. Doctors can also use corneal topographic mapping equipment to fit rigid contact lenses and make corneal shaping lenses.
Fundus examination
Fundus examination is an important method for evaluating the internal structure of the eye. Shanghai Eye Hospital is equipped with * advanced fundus cameras and OCT instruments, which can observe the blood vessels, retina, optic nerve and other parts of the fundus in real time, so as to detect changes and diseases of the eye.
Fundus examination is of great significance for screening and monitoring diabetic retinopathy, glaucoma, optic neuropathy and other diseases. This non-invasive examination method can provide doctors with detailed eye structure information, which is helpful for early diagnosis and treatment.
summary
Shanghai Eye Hospital provides various optometry services for patients through advanced instruments and methods. The top-down optometry can accurately measure the optical properties and refractive state of the eye through the application of special instruments. Routine optometry and corneal topography can help doctors determine the patient's refractive error and the degree of correction. Fundus examination can evaluate the internal structure of the eye, screen and monitor various eye diseases. Shanghai Eye Hospital has a comprehensive optometry method, which helps doctors accurately diagnose and treat various eye problems.
